# major

The major value from the beacon identity constraint that defines the beacon region.

## Declaration

```swift
@NSCopying var major: NSNumber? { get }
```

## Discussion

Discussion If you don’t specify a major value for the beacon, the value of this property is nil. Operations that compare a beacon’s identity characteristics with the constraint’s characteristics ignore the major value if this property is nil.
